Hi,
I'm a newb when it comes to antennas.

I previously designed a circuit board which contained a Chipcon CC2500 2.4GHz transceiver. It was using an inverted F antenna (pcb trace). The design included a balun and other matching components. I copied most of this from the reference design that was provided with the evaluation boards.

Now I want to use a Gigaant Rufa SMD antenna. If I obey the restrictions as far as distance from the ground plane and thickness of PCB etc, can I just replace the inverted F antenna with the Gigaant antenna? Do I need to change values of the matching components or balun?

Thanks!

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
